Abstract

A new control scheme for the class DE inverter is presented. This method generates the output voltage and power by varying driving signals which turn switches on and off. The advantages of the proposed scheme are the improvement of the power conversion efficiency for low output voltage, the operation at fixed operating frequency, unneccessity of enlargement of the circuit scale, and suitability for controlling the wide output range. An exact analysis and circuit experiments are carried out. It is shown that the experimental results are very similar to the theoretical predictions qualitatively. Measured efficiency is over 93% with 1.0-MHz 1.8-W output.
